Grind is a 2003 American skateboarding comedy film directed by Casey La Scala, and written by record producer Ralph Sall, who also composed the score. The film stars Mike Vogel, Vince Vieluf, Adam Brody and Joey Kern as four teenage aspiring amateur skaters trying to make it in the world of pro skateboarding by pulling insane stunts in front of their pro skater idol. It was critically panned and flopped at the box office, but has been received more positively by audiences.
